Damien Williams FAAB value

Damien Williams just hit waivers. I have $69 FAAB dollars left and need an RB. How much should I bid?

It is a 12 team, .5 ppr league

I’m in a 12 team .5ppr with $47 left and posted another topic asking if I should max out.
The more I think about it, the more I think I need to put my max.
Take a look around your league and see who you think will bid and what they have left.
If I were you and you need a RB I would do at least $50
